is there a way to block male viewer i want only woman to view my picture

No, anyone is free to peruse profiles.

You can, however, make your pictures 'Private'
and then send the link for the 'Private' pictures
to anyone you choose.

This is accomplished by clicking on the picture
you wish to make 'Private' (this places it in the
'Main' picture spot) which will then have the option
beneath it to make it 'Private.'

You may wish to think twice about making all your
pictures 'Private' as it can diminish 'Views.'
This is because on the Search engines, there is an
option to see only profiles with pictures.
